Question

Three students that share a townhouse find that their electric bill for October is $2.23 less than the September bill. The

total of both bills is $292.43, and each bill is split evenly among the roommates. How much did each owe in September?

Answer 1

$47.48

Explanation:

Let x = the amount owed Sept.

x + x - 2.23 = 292.43 Combine like terms

2x -2.23 = 292.43 Add 2.23 to both sides

2x - 2.23 + 2.23 = 292.43 + 2.23

2x = 294.66 Divide both sides by 2

`(2x)/(2)` =
`(294.66)/(2)`

x = 147.33 this is the bill for September

Oct. 147.33 -2.23 = 145.10 This is the Bill for Oct.

Total:

147.33 + 145.10 = 292.43

292.43 ÷ 3 = 97.48 This is what each will owe rounded to the nearest penny.
